PRINTING .ANITCALCULATING' MAGHIN E.

" son, a citizen of the United States,-residing at Brunswick, in the county of Glynn and State of Georgia, have invented certain new and useful Improvements in Printing-and Calculating Machines, of-wliich the following is a specification, reference being had to the accompanying drawing.

My invent onjel'ates to calculating and printing devices. One of the objects of my provide a machine for the forating the figures thereon. Anotherobj'ect is the computing or substra'ctlng of all checks written, from an origlnal balance or specified sum, and showing the result obv tained after each check is printed, this .be-

in fbi ating the figures. A further object is the keeping of an accurate balance shown on a dial on the instrument.

Another object is the provision of a'locking device, which automatically locks itself when such specified amounts have been subtracted and the amount of the balance is at zero. This function is intended to stand as a protection against the printing of more checks than a specified sum, orfoverdraft of a bank balance.

Toenable the invention to be readily understood, I shall firstdescribe the operation thereof, and then describe the mechanism whereby the objectsabove mentioned are attamed. p The indicating mechanism is in the form of two dials, 7 and 8, on the top of machine,

8 indicating the figures showing the amount of check to be stamped. This is the check reading dial. The second dial 7, which is the balance reading dial, indicates the specified balance or sum at which the machine is set. As an illustration, set the balance reading dial to SlIQW $1000.00, and wishing to write check-s of $100.00, $300.00, and $400.00 each proceed as follows:

For the $100.00 check start at the left hand decimal, showing the $100.00 column in the check reading dial, pull the finger slide toward the stamping lever 20, then setting the ciphers indicating one hundred on the left hand sideof the dollar period and twociphers on the right hand, indicating the cents column. A blank check .is th placed'in the cheek holder 90, which Specification of Letters Patent.

the form of a slide. After the check placed, this slide is placed in proper position to hold the check on the stamping dies. The stamping lever is now pressed down and released and returns to normal position, releasing the setting slides which also return to normal.

lVith this operation, the calculating device subtracts the $100.00 from the former balance of $1000.00, leaving $900.00 showing on thebalance reading dial 7. I

. The same operation being performed in the same manner will obtain the results of $600.00 showing on the balance reading dial after $300.00 has been stamped,.and $200.00 after the $400.00 check has been stamped. This would leave a balance of $200.00 showing on the balance reading dial.

An additional check for $200.00 or less, or as many checks as will make a sum total of $200.00may be written, but when this sum of $200.00 has been subtracted from the bal ance the machine automatically locks itself by means of a locking device placed in the machine, which may be controlled by a key inserted at 86*", this key allowing themachine to be reset to such amounts as may be.

in which Figure 1 is a top view of a deviceembodying my invention, Figs. 2, and 2, a side View partly in section of Fig. 1. Figs.'3 and 3, is a top View of the interior mechanism. Fig. 4, a view partly the device,

in section, at right angles to Fig.2, through the stamping mechanism, and Figs. 5, 6, 7 8, 9, 10, 11, and 12, detail views of parts of the device. Like figures of reference denote the same parts wherever shown.

The stamping device of the machine is composed of a series of bars 50. This series of bars are placed in the machine, side, as shown in the figures, with a unit and tens bar to represent the cents, then the side by ion , eriod space between these bars and the bars or the dollar columns. After the two bars representing the cents, we have the dollar units, tens, hundreds, thousands, etc. As many of these bars ihay be placed in the machine as to allow for aslarge size checks has a. ssries'or" figures, from 0 to 9, inclusive,

that may be desired. Each one of these bars spring catch 40, which automatically catches menace numerals in Fig. 2 as follows: GOrepresents 0, 61 represents 1,62 represents 2, and so on' I of the die representing 0, which is designated by the numeral 60, the distance in. front of the type representing 0 being the Width of one die, is laced iii the machine the stamping bar 31 ig. (2). This is made up'of a series of thin steel blades and embedded. witha hard rubber composition in a groove on the top of the stamping bar, the stamping bar being controlled by a series of lift levers which will be described in paragraph.

The type bars are controlled from the.

7 exterior of the machine by a series of finger slides or'slide levers, as shown on Fig. (1). These slide levers, indicated by. 80 and 81, Fig. (2), are used to slide the type over stamping bar, and are held in position by the e type bar and holds it in position over the stampingbar at the desired figure, the

catch to each bar.

%ries of catches and springs designated by the numerals 40. and 41, there being one This catch is so (3011]- structed and operated by the stamping lever 20 that when one check is placed in the ,machine and stamped, and the stamping lever goes back to its former position, it

. releases all of the series of catches 40 and elallowing all the type bars to go back to their former position, which guards against the stamping of more than one check with one setting of the machine. The type bars are so constructed that when the bars are moved forward to show a desired amount.

by the indicating figures on the bars 50 in the check reading dial 8 Fig. (2), the

type bars will be placed in such a position over the stamping bar 31 that the same amount'showing on the dial 8 will be over the stamping bar 31, thus stamping on the check the amount as shown on the check reading dial 3. p

The attachment placed at the end of typ bar under f the slide levers consists of a small expansion spring which pulls the type bar 50 when released back the width of one type beyond the stamping bar 31. This attachment is provided so as to prevent the computing device registering more than the desired amount and to prevent the 0 from being stamped at the left hand side of the figures of the check.

alater- 'voiving on shaft 38.

The tamping devii 'e is controlledby the stampi g lever 20 which. is fixed on two shafts 24 and er, there being-a series oi:

cams and lift bars, 21, 22, 23, 24.- for the cams. and lift bars 28 and 29 lifting bars 30 which bear under each end of stamping bar 31, there being a set of these cams and lift bars on each side of the machine so placed as to lift the stamping bar 31 against the type when the stamping lever is pressed down to stamp the check, th1s operation stamping and perforating the check.

Attached tothe shaft 248 is a cam 25 attached to a tension spring 26 which creates the tension on stamping lever 20 and pulls it back to normal position after the check is stamped and lever is released.

' There is also a cam 35 attached to shaft 24*, with rolling catch 36, which when stamping lever 20 is pressed down, drops under small cam lever 37 and when lever 20 is released the upward pressure forces the cam 37 to revolve the tripping cam 33", re-

The tripping cam presses on the series of catches indicated by the numeral 40, so that the final operation of the stampinglever' 20, being pulled back up to normal position releases-all of the type bars 50, thus restoring the machine to normal. The type bars 50, when released by the above operation, are pulled back to normal by means of tension springs 54.

The series of bars. represented by the numeral 51, Fig. (2) with the cog ear on the bottom edge, which when pulled .orward by the setting levers 80 and 81 and bars 50, revolve the ratchet cog gear 57 on shaft 56*, this ratchet-being constructed in such a manner as to only revolve the computing units 56, so that when the type bar 50 ismoved forward one figure, it revolves thecomputing unit 56, one tenth of a revolution, or as many tenths as represented by the figure to ,which the type bar 20 is set, via: if se'tat 5, the computing unit is revolved five tenths of .a revolution. Upon the right-handfa'ce of each unit 56 is a gear (see Fig; 2*);

and on the left-hand face'of each unit are three cogs 111 which represent one-tenth of a complete revolution of the unit; Loosely mounted on a shaft 58*, and located between the adjacent units 56, are cog gears 58 which are at all times in mesh with the teeth 110, and with which cogs 111 mesh when the lit unit to which they are attached is rotated. rec

lVith this arrangement, upon rotation of one unit through a'coinplete revolution the cogs 111 of this unit will be brought into engagement with the gear 58 causing the same to rotate the next succeeding unit. An

inspection of Fig. 3 will show that'the gears 58 are of appropriate width to engage thegear 110 at all times and to be engaged by the teeth 111 as they approach. Thus, with each complete revolution of the computing 13c unit, the next higher decimal of the com puting units, or the next one to the left. is revolved one tenth "oi-a rcvolution, thus carrying or transferring theamounts from one decimal unit to, the next forward computing uniti, A sectional detail of thecomputing units is shown bytbe-Figs. (8), (7), (8) and (9), and a sectional detail of the revolving vratchet is shown by Figs, -{1.0), (I1),- and (12), this ratchetgrevolv-ing on the same shaft as the computing-.unit and working in rongilmction withthe slide bars revolves the comnuting unit only in one desired directhese units working in conjunction with other by means (a a series of cog gears aid the subtracting result being obtained oy simply placing the figures on the computin this manner acting as a subtractor.

' The locking device is controlledby a key which may be inserted at 86 and which ongages a member 86 pivoted at one end and pressed by spring 87 at its other end and as each of the remaining units revolves totlie same position they are in turn locked atically; that is, when all the computing units stand at the entiremacliine is automatically locked. The lzeyfor actuatall beiicg'set with the maximum desired. As

soon as the setting is complete the key is turned )ermitting the lock86 to lie in the path o'f the teeth lll and engage the-same at t 1e expiration oil-lie registering function by the setting. 1t will be evident W s i'ncclianism provides for the funcn of the printing and registering. de-

so long the latter is free from of the lock. As soon the regls are exhausted by the successive 1c is ofthe type bars, the lock-be, comes effective and the machine prevented from further use until such time as the lock :ased the registering mechanism l I: parts oi the locking ilili in conjunction with it, its a series or tumblers These in )lers "aerate to prevent the slides being set only nileft right of the machine. These nblers operate so that when the bar moved forward to any figure to be stamped, it revolves these, each tumbler in urn revolving all. the tumblers to the left,

and causing the locking bar to drop units to read downward or from 9 to 0- and cylinders 101. and

spring bar 85 and the lock or latch down in. front of the ends of all the remaining bars 50 to the left of the bar thus moved, making it Impossible to set any of the type printed on the checks.

The chck holding slide 90 operating in slot 14, on the guide tracks 13 and 13 is so constructed thatwhen it is desired to place the blank check in the machine this slide is pulled out of the machine to a point where the check can be easily placed in the slide under the holder 91. Actuated by the springs 88 and 89, theholder 91 holds down the check in the slide in the desired position. The slideand holder are provided with slots 93 and 94, so as to allow the stamping bar. 31 to pass through these slots and pressthe check against the type.

The check slide operates the ribbon attachmeiat, the ribbon attachment being shown by the dotted line 98 passing through the spring clamp 92 which only operates the ribbon in onedirection, thus renewing the ribbon under the type each time thefslide is pushed in to insert the check. The ribbon attachment com rises a spool 99 for unwinding, and a. win in spool 100 placed on the 102,; the" ribbon being wound. on to the winding spool by means of the friction beltv 104 revolving the cylinder 101 as the cylinder 102 isrevolved by the ribbon bein ul led oil this s 001 by 100 the operation o the check slide. he unwinding cylinder having a larger pulley than the winding pulley, it-by means of the friction belt 104 keeps a tension on the rib.- bon as it passes over the type. The clamp 92 has a free end directed toward the inner end of the slide 90, and this free end'of the clamp engages against the overturned edge of'the end of the slide so that when the slide is pulled outwardly, movement-of the ribbon is not effected, but when the slide is pushedinwardly the end of the clamp tends to bite into the ribbon'so that theribbon is gripped between the clamp and the overhanging flange or edge of the slide and the ribbon will be unwound from the spool 102 and wound upon the spool 101.
